Compiling QtRuby

[Hector]

I've been trying to compile Qt Ruby without success.
I've got Qt 4.1.1 installed and it tested fine. I was able to run the
demos without a problem.

When I try to compile qt4-qtruby-1.4.3 I get this:

<Abstract>
-c -o qtrubyinit.o `test -f 'qtrubyinit.cpp' || echo
'./'`qtrubyinit.cpp; \
then mv ".deps/qtrubyinit.Tpo" ".deps/qtrubyinit.Po"; \
else rm -f ".deps/qtrubyinit.Tpo"; exit 1; \
fi

I know almost nothing about compiling C++ programs, does anyone know how
I can get around this problem.


Thank you.

A question from a non-Qt user. Does Qt Ruby try to match version
numbers with Qt. For example is qt-qtruby-1.4.3 meant to be used with
any qt-1.4.x ?

Was your compilation from a *.tar.gz file? or did it come from
installing a *.gem file?
